Ken, I never peel new potato's but have discovered quite a few uses for my pressure washer besides giving me pristine white paves.
With the long handle the Conservatory roof gets a polish without needing a ladder and it is the full length of the house.
When I removed ivy from the wall after many years I found it difficult to remove those small wisps of root from the brickwork. Holding the pressure pipe at a very narrow angle to the bricks it removed and cleaned the bricks without water logging them, the chap over the road cleaned his bricks with a scrubbing brush and water taking nearly a week, mine took two hours.
Apart from its many uses it keeps the grandkids amused and very wet, I am in the kitchen and can turn the outside tap off before going to get them and clean them up, as I said many uses.
